Command
Step 3
snmp-server enable traps mac-notification
Step 4
mac-address-table notification
Step 5 mac-address-table notification [interval value] |
[history-size value]

To disable the switch from sending MAC address notification traps, use the no snmp-server enable
traps mac-notification global configuration command. To disable the MAC address notification traps
on a specific interface, use the no snmp trap mac-notification {added | removed} interface
configuration command. To disable the MAC address notification feature, use the no mac-address-table
notification global configuration command.
This example shows how to specify 172.20.10.10 as the NMS, enable the switch to send MAC address
notification traps to the NMS, enable the MAC address notification feature, set the interval time to 60
seconds, set the history-size to 100 entries, and enable traps whenever a MAC address is added on Fast
Ethernet interface 0/4.
Switch(config)# snmp-server host 172.20.10.10 traps private
Switch(config)# snmp-server enable traps mac-notification
Switch(config)# mac-address-table notification
Switch(config)# mac-address-table notification interval 60
Switch(config)# mac-address-table notification history-size 100
Switch(config)# interface fastethernet0/4
Switch(config-if)# snmp trap mac-notification added
You can verify the previous commands by entering the show mac-address-table notification interface
and the show mac-address-table notification privileged EXEC commands.
